The guava trees were sprayed with 0.0%, 0.2% and 0.4% iron sulphate in July 1966 and 1967. It was observed that iron spray in 0.2% and 0.4% concentrations was highly capable to cause significant increase in various characters. The maximum increase in extension of terminal shoots, number of leaves, leaf area per shoot, chlorophyll recovery and yield was observed under 0.4% spray. Maximum increase in fruit weight, length and diametre was noted under 0.2%. Maximum effect of acidity, non reducing sugars and Vit.
